Streaming AR0144 ( ap1302) in iMX95 Verdin Evaluation Kit

Harish_V — Tue, 14 Oct 2025 06:28:38 GMT

I am working on iMX95 Verdin evaluation kit, I am trying to port ap1302 which was given default support. I have copied the firmware .bin from git and have placed it inside /lib/firmware. The camera gets detected and 3C gets utilised in i2c bus 2 , I am unable to stream the camera. Do we have to set any media bus ? Has anyone come across this issue ? Kindly do let me know the solution for this. Thanks.

I am using the v4l2-ctl -d 0 --stream-mmap command.

I have currently flashed the board with the default package.
For Alpha - A1 Silicon:
sudo ./uuu -v -b emmc_all ./imx-boot-imx95-a1-19x19-verdin-sd.bin-flash_all \
./imx-image-full-imx95-19x19-verdin.wic

I am using the imx95-19x19-verdin-lt8912-ap1302.dtb

In i2cdetect -y -r 2 , 3C and 34 is getting UU utilised.

When i give stream on I get ,
VIDIOC_QUERYCAP: ok
VIDIOC_REQBUFS returned 0 (Success)
VIDIOC_CREATE_BUFS returned 0 (Success)
VIDIOC_QUERYBUF returned 0 (Success)
VIDIOC_QUERYBUF returned 0 (Success)
